Most of the studies on real nanostructured oxides are based on materials not having a well-defined 3D structure (both on short and long-range), being composed of irregularly shaped nano-crystals. These materials are polycrystalline, and show several nano-interfaces, which stabilize... 

Although the discussion reported here will be mainly in reference to titania nanostructured films, the opportunities and problems analyzed are of more general interest and regard how to use the concept of bidimensional nanostructured oxide films to prepare novel catalysts with tailored nano-architectures.

In this chapter, we would like to present the most interesting and important (from our point of view ) results obtained by the EPR technique for colloidal and nanostructured oxide semiconductors. Kinetic, photocatalytic, PEC and spectroscopic data will be performed in addition when necessary. Below, for easier understanding of the EPR terms by the readers, we will explain shortly some basic principles of the method.

In an interesting interplay between GO and organosilanes (which are so extensively used to modify amorphous or nanostructured oxide surfaces), there are reports [33], of the preparation of intercalation compounds in which amino groups are inserted into the interlayer space of GO, using 3-aminopropylethoxysilanes. For such compounds, it was shown that the amino groups of... 

This chapter has presented the current status of electrochemical, impedi-metric and field-effect solid-state gas sensors for CO2 detection. As can be inferred from the works reviewed, although there are already some electrochemical devices for CO2 detection in the market, there is significant room for improvement and new detection principles to investigate in order to realize cheaper and more reliable low-cost CO2 solid-state sensors. Researchers try to improve sensitivity, selectivity and long-term stability of the devices by exploring new fabrication methods that are cheap and reliable. As presented in Section 16.5.2, nanostructured materials are becoming more popular because of their improved sensing properties. Other approaches, such as the UV stimulation of metal oxide materials (also of nanostructured oxides), open new possibilities for room-temperature detection.
